How do I setup MOQ without Repository? System.NullReferenceException: 'Object reference not set to an instance of an object

Question

This is the constructor of my test class

public IngestServiceTest()
{
    IConfiguration configuration = new ConfigurationBuilder().AddJsonFile("appsettings.test.json").Build();
    _logger = LoggerFactory.Create(builder => builder.AddConsole()).CreateLogger<object>();
    
    var fileProcessLogDbSetMock = new Mock<DbSet<FileProcessLog>>();
    mockDowJonesContext.Setup(s => s.FileProcessLogs).Returns(fileProcessLogDbSetMock.Object);
    ingestService = new IngestService(mockDowJonesContext.Object, configuration, _logger);
}

But it hits System.NullReferenceException: 'Object reference not set to an instance of an object.' at mockDowJonesContext.Setup(s => s.FileProcessLogs).Returns(fileProcessLogDbSetMock.Object);

I see many tutorial but it is with Repository but mine is without Repository.
